Can we deploy an asp.net mvc 4 app to docker with windows container?

Question

All the demo I saw lately are oriented Asp.net core (I am not sure how it\'s stable and functional, as it didn\'t contain all asp.net features), as Windows server 2016 suppo

Answer 1

Yes.

You can use microsoft/windowsservercore or microsoft/iis as a base image, install full ASP.NET and run your 'legacy' .NET apps in containers on Windows. You can do it now with Windows 10 and Server 2016 TP5, but the RTM (expected next week at Ignite) should be more stable.

I've shown this by Dockerizing the old Nerd Dinner showcase app. You end up with a Docker image that's 3GB so you won't get all the benefits of having a small, efficient image - but you can run your app in a container, and that's a starting point for breaking down monoliths.

For reference, this is what the Dockerfile for a compiled ASP.NET app looks like:

FROM microsoft/iis

RUN ["powershell.exe", "Install-WindowsFeature NET-Framework-45-ASPNET"]
RUN ["powershell.exe", "Install-WindowsFeature Web-Asp-Net45"]

ADD web-app/ c:\\web-app

EXPOSE 8081

RUN powershell New-Website -Name 'web-app' -Port 8081 -PhysicalPath 'c:\web-app' -ApplicationPool '.NET v4.5'

ENTRYPOINT powershell
